Materials
  • 5 test tubes
  • Small piece of copper
  • Small piece of aluminium
  • Small piece of zinc
  • Small piece of iron,
  • steel wool
  • rubber stoppers
  • stop watch
  • safety goggles
  • thermometer
  • 25 cm of 2m Hydrochloric Acid
Procedure

  1. Gather all materials.
  2. Pour approximately 5 cm of 2M Hydrochloric Acid into a test tube.
  3. Measure the temperature of the acid.
  4. Clean a piece of zinc with the steel wool until it is shiny.
  5. Add zinc to the test tube
  6. Loosely seal it with a rubber stopper.
  7. Begin timing the reaction as soon as the metal is added.
  8. Record visual observations (ex. presence and rate of bubbles) and the times they occurred at.
  9. Stop timing when reaction ends (or after 5 minutes).
  10. Measure the temperature of the acid after the reaction has occurred.
  11. Repeat step 2 but in a different test tube
  12. Repeat step 3 once
  13. Clean a piece of Aluminium with steel wool until shiny.
  14. Add aluminium to the test tube
  15. Loosely seal it with a rubber stopper.
  16. Begin timing the reaction as soon as the metal is added.
  17. Repeat step 8 once
  18. Repeat step 9 once
  19. Repeat step 10 once
  20. Repeat step 11 but in different test tube
  21. Repeat step 12 once
  22. Clean a piece of iron with steel wool until shiny
  23. Add iron to test tube
  24. Loosely seal it with a rubber stopper
  25. Begin timing the reaction as soon as the metal is added.
  26. Record visual observations (ex. presence and rate of bubbles) and the times they occurred at.
  27. Stop timing when reaction ends (or after 5 minutes).
  28. Measure the temperature of the acid after the reaction has occurred.
  29. Repeat step 20 but in different test tube
  30. Measure the temperature of the acid.
  31. Clean a piece of copper with steel wool until shiny
  32. Add copper to test tube
  33. Loosely seal it with a rubber stopper
  34. Begin timing the reaction as soon as the metal is added
  35. Record visual observation
  36. Stop timing when reaction ends
  37. Measure the temperature of the acid after the reaction has occurred.
